Abstract : The double layer capacitance (DLC) of porous zinc electrodes in 31 percent KOH was measured by both the potential step method and the potential sweep method at -40C. The methods yielded similar results, but the potential step method provides additional useful information about the charging process of the double layer. Relating the DLC data to the gravimetric BET (gas absorption method) surface areas yielded a specific capacitance for porous zinc at -40C. (Author)
